auv-wayland-rendering

auv-wayland-rendering is a skill for Codex from moeru-ai/auv. It costs 107 tokens per session (1,472 once invoked), scanned A, original, Apache-2.0.

A guide for preparing and checking Linux graphics sessions that use Wayland, a Linux display system, and PipeWire, a service for handling audio and video streams. It covers AUV rendering and screen capture through desktop portals, including remote and headless setups.

In plain words
What is it for?
It is used to inspect systems, configure a Wayland session, run validation probes, and troubleshoot capture failures.
Why use it?
It helps diagnose missing graphics dependencies, compositor problems, blank captures, and uncertainty about hardware rendering without overstating support.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

auv-wayland-rendering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/probe-wayland.sh, scripts/verify-auv-capture.sh, scripts/with-wayland-session.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AUV Wayland Rendering

Build a reproducible Linux desktop session in which AUV can observe a Wayland display and persist capture artifacts. Treat environment validation as evidence, not as a change to AUV's public support claim.

Keep ownership explicit: the compositor renders application clients; AUV requests frames through the portal and records them. Do not imply that AUV ships the compositor or a Linux overlay renderer.

Read the relevant references

  • Read setup.md before installing packages, creating a compositor session, or configuring remote viewing.
  • Read troubleshooting.md when a probe or capture fails, the image is blank, or hardware rendering is uncertain.
  • Check AUV's current support matrix before describing a result as supported. A successful live probe is live-validated evidence for the named environment only.

Follow the workflow

1. Inspect before changing the host

Run the read-only probe in the target shell:

.agents/skills/auv-wayland-rendering/scripts/probe-wayland.sh

Add --require-gpu to make missing GPU prerequisites fatal when hardware rendering is required. The flag does not replace compositor-log evidence. Record:

  • distribution and package manager;
  • existing compositor and whether the session is local, nested, or headless;
  • WAYLAND_DISPLAY, XDG_RUNTIME_DIR, and the session D-Bus;
  • accessible /dev/dri/renderD* nodes and the renderer reported by compositor logs or eglinfo/vulkaninfo;
  • ScreenCast portal and PipeWire readiness.

Do not infer GPU rendering from the presence of a GPU or render node. Require a renderer log or renderer-tool result. Label pixman, llvmpipe, and similar paths as software rendering.

2. Choose the session shape

Prefer the existing logged-in Wayland compositor when one is available. It already owns the seat, GPU, D-Bus activation environment, and user consent UI.

Use headless Sway when the host has no desktop session or the test must be isolated. Start with wlroots renderer auto-selection. Force pixman only as an explicit software fallback; doing so gives deterministic rendering but does not validate the GPU path.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
